Wolverhampton Wanderers are thought to be willing to invite Sunderland and Stoke City to step up their pursuit of Steven Fletcher this week after signing a replacement.
The Scotland international is understood to be a target for a few Premier League sides, with Stoke having already asked about the striker's availability.
Sunderland are also interested in the ex-Hibernian striker, who scored seven headed goals last season - the most by any player in the Premier League.
Wolves boss Stale Solbakken confirmed the signing of Iceland international striker Bjorn Bergmann Sigurdarson from Lillestrom for £2.4m, meaning that the club are likely to cash in on Fletcher.
Officials at Molineux believe they can command a fee of around £10-15m for Fletcher, who boasts a respectable top-flight goal return of 22 in 61 matches.
The Midlands club are hoping to recoup a large amount for the 25-year-old after goal scorers such as Darren Bent and Andy Carroll moved clubs for record fees.
Fletcher joined Wolves from Burnley in 2010 for £6.5m.
